Why Do My Legs Ache at Night?
If you frequently wake up with aching or throbbing legs, you're not alone. Many people experience leg pain at night for a variety of reasons. While occasional leg cramps or growing pains are usually harmless, persistent nighttime leg pain can indicate an underlying health issue that needs treatment.
In this comprehensive guide, we'll discuss the most common causes of nighttime leg pain and provide tips to help you find relief so you can sleep better.
Common Causes of Nighttime Leg Pain
Here are some of the most frequent explanations for why legs hurt at night:
Muscle Cramps
Muscle cramps are involuntary contractions that occur when a muscle suddenly spasms and becomes tight or knotted. They most often affect the calves, thighs, and feet.
Cramps can last from a few seconds to up to 10 minutes. They can range from mild to extremely painful.
Muscle cramps typically happen while you're lying down and resting. They tend to strike just as you're falling asleep. Besides being painful, cramps can jolt you awake.
Common triggers for nighttime leg cramps include:
- Dehydration or electrolyte imbalances
- Poor circulation
- Working calf muscles extensively during the day
- Standing for long periods
- Pregnancy
- Medications like diuretics
- Medical conditions including arthritis and nerve, liver, or thyroid disorders
Restless Legs Syndrome
Restless legs syndrome (RLS) is a condition that causes unpleasant sensations in the legs. These sensations typically occur when lying down and trying to sleep.
People describe RLS sensations in different ways. You may feel creeping, crawling, itching, pulling, throbbing, tingling, or like your legs are full of energy. The sensations make you feel like you constantly need to move or stretch your legs.
RLS can range from mild to intolerable. Symptoms usually worsen in the evenings and nights. The unpleasant feelings disrupt your sleep by preventing you from falling asleep or waking you up.
The exact cause of RLS is unknown. However, it appears to involve a malfunction in the way the brain uses dopamine. RLS has links to iron deficiency, pregnancy, end-stage renal disease, Parkinson's disease, and certain medications.
Leg Cramps and Restless Legs Syndrome
Leg cramps and restless legs syndrome are two different conditions, but they share some similarities. Both involve unpleasant leg sensations that start or worsen at night when lying down.
However, RLS sensations usually affect both legs and produce an irresistible urge to move. Cramping is usually more intense but concentrated in a single muscle or muscle group. Cramps don't cause the urge to move.
Growing Pains
Growing pains are recurrent leg pains that occur in physically active children, typically between the ages of 3 and 12. The pain most often flares up at nighttime.
The cause isn't fully understood but likely involves normal growth and development. Bones grow faster than muscles and tendons, which leads to muscle tightness and aches.
Growing pains usually affect both legs, especially around the calves, thighs, or behind the knees. They're described as a sore, throbbing, or "pulled" feeling. Moving helps provide temporary relief.
Peripheral Artery Disease
Peripheral artery disease (PAD) happens when plaque builds up in the arteries that carry blood to the legs and feet. This causes reduced blood flow, which can lead to leg pain when lying down.
People with PAD often describe the pain as aching, cramping, numbness, weakness, or heaviness in the legs and feet. Symptoms usually appear during rest and improve with movement.
Walking may initially trigger pain and cramping that goes away with more walking. As PAD progresses, pain can become constant.
Major risk factors for PAD include smoking, diabetes, high blood pressure, high cholesterol, obesity, and older age.
Deep Vein Thrombosis
A deep vein thrombosis (DVT) forms when a blood clot blocks flow through a deep vein, usually in the leg. Symptoms often start in just one leg and include:
- Pain or tenderness
- Swelling
- Skin that feels warm
- Reddish or blueish skin discoloration
The pain and swelling of DVT typically worsen with standing or walking and improve with rest and leg elevation. A piece of the clot can break off and travel to the lungs, causing a life-threatening pulmonary embolism.
Major DVT risk factors include prolonged immobility, recent surgery or trauma, active cancer, obesity, smoking, pregnancy, and birth control pills or hormone therapy.
Arthritis
Osteoarthritis and rheumatoid arthritis - two common forms of arthritis - can both cause leg pain at night. The time of day doesn't impact arthritis pain. But symptoms may seem more noticeable when lying down quietly.
Arthritis pain ranges from mild to severe. It often includes joint stiffness, swelling, and tenderness. The knees, ankles, and hips are most prone to arthritis.
Fibromyalgia
Fibromyalgia is a chronic condition characterized by widespread muscle pain and tenderness, fatigue, mood issues, and sleep problems. Leg pain is one of the most frequently reported fibromyalgia symptoms.
People with fibromyalgia often describe deep muscle aching, throbbing, cramping, or burning sensations throughout their lower body. Symptoms are generally more severe upon waking and improve during the day.
While not life-threatening, fibromyalgia can severely impact quality of life. The intensity of pain and fatigue tends to fluctuate in cycles.
Nerve Compression
Pressure or damage to a nerve can produce leg pain described as sharp, shooting, burning, pins and needles tingling, or numbness. Symptoms often radiate down part or all of the leg.
A herniated disk or bone spurs in the spine can compress nerves traveling to the legs. This is often called sciatica. Carpal tunnel syndrome involves compression of the nerve at the wrist.
Diabetes is a common cause of nerve damage (diabetic neuropathy) leading to leg and foot pain, especially at night. Other potential causes include vitamin deficiencies, alcoholism, infections, tumors, and autoimmune disorders.
When to See a Doctor
Occasional minor aches and pains in the legs are normal and usually not a concern. However, see your doctor if you experience:
- Frequent or persistent leg pain that disrupts sleep
- Intense calf pain accompanied by swelling
- Leg pain only at night or pain that keeps worsening
- Weakness, numbness, or tingling in the legs
- Leg pain after an injury or trauma
- Leg pain along with shortness of breath and an irregular heartbeat
Severe or recurring leg pain, especially at night, may signal potentially serious health issues that require prompt medical care. Don't ignore symptoms or simply try to live with the discomfort.
Tips for Relieving Nighttime Leg Discomfort
In many cases, you can find some relief from leg pain at night with self-care measures at home. Try these tips:
Stretch and Massage
Gentle stretching can help reduce muscle tension and cramping. Try exercises like ankle rolls, knee-to-chest pulls, calf stretches, and hamstring stretches twice a day.
Massaging sore muscles stimulates blood flow and soothes aches. Use light, kneading strokes focusing on the calves, thighs, and feet before bedtime.
Apply Heat
A warm bath or heating pad can relax tight muscles and increase circulation. Taking a warm shower before bed may help you fall asleep more easily.
Use Cold Therapy
Applying an ice pack to sore leg muscles reduces inflammation and numbs pain signals. Try icing for 10-15 minutes a few times per day.
Get Moving
Light physical activity increases blood flow to the legs. Take short walks periodically during the evening before going to bed.
Elevate Your Legs
Lie down and raise your legs above the level of your heart for 10-15 minutes, 2-3 times per day. This improves circulation and reduces swelling.
Improve Leg Circulation
Quit smoking, manage chronic health conditions, exercise regularly, drink enough water, wear compression stockings, and avoid long periods of standing or sitting still.
Check Your Medications
Some medications like statins, antidepressants, and blood pressure drugs can cause leg pain. Talk to your doctor about alternatives if a medicine you take seems to aggravate symptoms.
Practice Good Sleep Habits
Get on a regular sleep schedule, limit naps, avoid screens before bedtime, sleep in a cool, quiet, and comfortable environment, and manage stress.
Try Natural Remedies
Supplements like magnesium, vitamin D, turmeric, and ginger may help reduce muscle cramps and pain. Consult your doctor before starting any new supplement.
Medical Treatments for Night Leg Pain
If at-home remedies don't provide lasting relief for persistent leg pain at night, your doctor can provide further help. Treatment options may include:
Medications
Muscle relaxants, pain relievers, or drugs to improve nerve function or circulation may be prescribed. Medications specifically for restless legs syndrome are also available.
Compression Stockings
These elastic stockings promote blood flow and reduce swelling in the legs.
Lifestyle Changes
Your doctor may recommend losing weight, exercising more, quitting smoking, eating healthier, and managing blood sugar if you have diabetes.
Surgery
Procedures to open blocked arteries or repair compressed nerves can resolve severe leg pain in some cases.
Vascular Treatments
Angioplasty, stents, or bypass surgery boosts blood flow by clearing or rerouting blood vessels damaged by PAD.
The Bottom Line
If nighttime leg pain is interfering with your ability to fall asleep and stay asleep, don't ignore it. See your doctor to determine the underlying cause and appropriate treatment. Often, a combination of lifestyle changes, home remedies, medication, or medical procedures can help you manage symptoms for more comfortable nights.
Getting to the root of leg pain allows you to treat it properly so your legs can feel better and you can rest easy.
